The domain will be every integer from 0 to 76867 (it will look like this [0, 76867].
The range will be {0, 161, 322, 3(161), 4(161), ... 76867(161)}.
With the information given, the equation will look like this:
f(x) = 161x
The domain is a set of all possible values that, when plugged into x, will give us a real number. So, if we were to plug in 2 for x, the equation would look like this:
f(2) = 161(2) = 322
Since 322 is a real number, 2 is part of the domain.
While the domain is the set of numbers that substitute x, the range is the product. So in the above example, the range would be 322. Since the domain is [0, 76867], the range would be the set of products that come from plugging in each of these numbers:
{0, 161, 322, 3(161), 4(161), ... 76867(161)}
